the practice of confession. He has also been shown to consider birth out of wedlock to be a sin. Gus has a very refined sense of smell and has nicknamed his nose "the Super Sniffer". He is able to recognize the base component of a perfume by smelling it and can perform the same trick with food. The talent seems to be hereditary, as it has been displayed by both of his parents, and has led to the uncovering of crucial evidence in several cases. He has been shown to have a fear of dead people, having run away from a scene where a dead person is present on more than one occasion. He has showed the dislike of seeing blood on occasions. He is also well-versed in high-tech locks or safes, as demonstrated by his ability to crack an electronic lock on his first try.
